Definitions

  • This invention relates to an article wrapped with a wrapping film, and more particularly to a wrapped article in such a form that a wrapping film is attached in close contact with an object to be wrapped, for example, a wrapped article which contains one or a number of objects such as a magnetic tape cassette housed in a case.
  • the product is wrapped with a transparent or translucent wrapping film coated with cellophane, polyethylene, polypropylene, polyvinylchloride, polyvinylidenechloride, or the like, in order to protect the product from dust or moisture and so maintain a good appearance.
  • These magnetic tape cassettes are shipped as a wrapped article or displayed in the shop as one of a number of packages to be sold en block in which an appropriate number of goods are collectively packed.
  • this tearing tape 2 allows a wrapping film 1 to be appropriately split and separated by pulling an exposed end 2a of the tape 2. Slits 3 are cut along this tearing tape in the vicinity of the exposed end 2a, thereby facilitating the removal of the tape.
  • the wrapping film 1 can be split along the tearing tape 2 from the end 2a. As a result of this, the wrapping film 1 is split up completely or separated in two.
  • a wrapping method which is generally called shrink-wrap is widely used for such a wrapping film.
  • shrink-wrap when a wrapping film is attached to an article to be wrapped (i.e. a product), the product is enclosed in the wrapping film while the film is appropriately stretched, or is heated to a suitable temperature, after the product has been wrapped, in accordance with the material of the film.
  • the wrapping film is tightly attached on to the surface of the product because of a contracting action of the film, so that the product is enclosed giving it a good appearance.
  • Such tight attachment of the film to the product involves a laborious removal action to open the film.
  • Conventionally, several measures are taken to overcome the drawback in the prior art by, for example, forming the tearing tape as mentioned above. This tearing tape was a very effective means.
  • the primary object of this invention is to provide a wrapped article which requires neither special machines nor members; and which enables easy removal of a wrapping film and easy access to an article enclosed in the wrapping film by widely tearing off the wrapping when the film is opened.
  • a wrapped article including an article to be wrapped whose outer surface is covered with a wrapping film and a body seal section created by making ends of the wrapping film overlap with each other and bonding them together, the improvement comprising: a removal tab portion made up of two slits that are spaced apart from each other by a given interval and cut along the edge of the body seal section of an upper wrapping film of the wrapping film in the body seal section; and at least one perforated section or indentation which starts from a point at which the perforated section or indentation and an imaginary continuation from at least one of the two slits of the removal tab cross, and which extends in a direction moving away from the imaginary continuation of the other slit.
  • a wrapped article including an article to be wrapped whose outer surface is covered with a wrapping film and a body seal section created by making ends of the wrapping film overlap with each other and bonding them together, the improvement comprising: a removal tab portion made up of two slits that are spaced apart from each other by a given interval and cut along the edge of the body seal section of an upper wrapping film of the wrapping film in the body seal section; and at least one first perforated section or indentation which starts from a point at which the perforated section or indentation and an imaginary continuation from at least one of the two slits of the removal tab cross, and which extends in a direction moving away from the imaginary continuation of the other slit; and at least one second perforated section or indentation which starts from a point at which the second perforated section or indentation and the imaginary continuation from the other slit cross, and which extends in a direction moving away from the first perforated section or indentation.
  • a wrapped article including an article to be wrapped whose outer surface is covered with a wrapping film and a body seal section created by making ends of the wrapping film overlap with each other and bonding them together, the improvement comprising: a removal tab portion made up of two slits that are spaced apart from each other by a given interval and cut along the edge of the body seal section of an upper wrapping film of the wrapping film in the body seal section; and at least one first perforated section or indentation which starts from a point at which the perforated section or indentation and an imaginary continuation from at least one of the two slits of the removal tab cross, and which extends in a direction moving away from the imaginary continuation of the other slit; and at least one second perforated section or indentation which starts from a point at which the second perforated section or indentation and the imaginary continuation from the other slit cross, and which extends parallel to the first perforated section or indentation.
  • a point at which the perforated section or indentation and an imaginary continuation cross used herein implies not only the state in which the perforated section or indentation crosses the imaginary continuation but also the state in which the perforated section or indentation lies in line with the imaginary continuation.
  • the front surface or the back surface of the removal tab is printed in ink that is different from the wrapping film in coefficient of thermal contraction.
  • the removal tab may be provided with a mark that makes the removal tab distinctive and indicates a peeling direction.
  • the removal tab consisting of the two slits is held with fingers or picked up with a fingernail, or the like.
  • the removal tab thus picked up is then pulled in a direction which is substantially orthogonal to the body seal section, and hence the wrapping film is peeled off from the removal tab and is torn up along the imaginary continuation from one of the slits.
  • a split developing from one of the slits reaches the foregoing perforated section or indentation, and stretches along this perforated section or indentation.
  • This perforated section or indentation is formed in such a fashion that it moves away from the imaginary continuation from the other slit, and hence the perforated section or indentation from the removal tab largely spreads. This causes the wrapping film to be widely opened, and hence it becomes very easy for a user to remove the film so that the entire wrapped article can be substantially uncovered.
  • the second perforated section or indentation is formed in line with the imaginary continuation from the other slit, and hence the split from the removal tab spreads much wider, whereby the wrapping film can be removed more easily.
  • the front or rear surface of the removal tab is printed in ink that differs from the wrapping film in thermal coefficient of contraction.
  • the removal tab is warped concavely or convexly with respect to the front or rear surface of the wrapping film because of a difference in coefficient of thermal contraction. For this reason, the removal tab becomes much easier to pick up, and the split from the removal tab is given the linearly advancing characteristic, whereby the wrapping film can be removed more easily.
  • the removal tab should preferably be provided with a mark to make clear the position of the removal tab and a peeling direction, and hence the position from which the wrapping film is removed becomes clear.
  • Figure 1 is a schematic representation showing a wrapped article according to a first embodiment of the present invention in which a video cassette is to be wrapped.
  • a wrapping film 1 overlaps with each other at substantially the center of a wider surface of a rectangular parallelopiped article to be wrapped 10 which is a video cassette (when it is encased in a housing case), and heated and welded together to constitute a body seal section 4 (this body seal section will be herein designated by a slanting line). Both ends of the body seal section 4 are welded together with the other sides of the film so as to reach a side seal section 13.
  • the body seal section 4 and the side seal section 13 where both ends of the wrapping film 1 overlap with each other are welded by appropriate heating after the article to be wrapped 10 has been wrapped.
  • a removal tab 7 is made at a position close to the longitudinal end of the body seal section 4 along its marginal line in an upper overlapping film of the wrapping film 1.
  • This removal tab is formed by the combination of slits 5 and 6 which are cut at right angles to the marginal line in the upper overlapping film in such a way that they are spaced apart from each other by a given interval and parallel to each other.
  • a perforated section 8 is formed in such a way that it crosses an imaginary continuation from the slit 6 of the removal tab 7 and extends away from the imaginary continuation from the slit 5.
  • the split formed by such tearing actions makes it possible to cause tearing actions in such a way that the split will continue around the wrapping film 1 by pulling the removal tab 7 formed in the upper overlapping film and tearing the film. Thereby, the wrapping film 1 is opened more widely, and hence the film 1 can be peeled off in such a way that substantially the whole wrapped article 10 is extremely easily uncovered.
  • the removal tab 7 is created in the vicinity of the surface on which the side seal section 13 of the wrapped article 10 is formed. Therefore, a part of the wrapping film 1 remaining on the surface on which the side seal section 13 is formed can be extremely easily taken off by pulling the remaining wrapping film in the direction in which it is removed.
  • the wrapped article of this invention allows an extremely effective removal operation by a single action, and eliminates the necessity of using the tearing tape, thereby rendering this wrapped article very cost effective.
  • FIG. 4 shows a wrapped article of this embodiment.
  • a wrapped state of the wrapping film 1, the slits 5 and 6, the removal tab 7 and the perforated section 8 are the same as those of the first embodiment, and hence the detailed explanation thereof will be omitted here for brevity.
  • a second perforated section 8' is created in line with an imaginary continuation from the slit 5.
  • the removal tab 7 is initially held with fingers or picked up with a fingernail or the like, and the fingers are moved to the A direction as shown in Figure 4. In the same manner as in the first embodiment, this causes the wrapping film 1 to be torn up from the slits 5 and 6 that constitute the removal tab 7, and the removal tab 7 is lifted off from the lower overlapping film, so that the split from the slit 6 reaches the perforated section 8. Together with this, the split from the slit 5 reaches the perforated section 8'.
  • the creation of the second perforated section 8' in line with the slit 5 facilitates the opening of the wrapping film 1 to a much greater extent.
  • Figure 5 shows the wrapped article of this embodiment.
  • a wrapped state of the wrapping film 1 the slits 5 and 6 and the removal tab 7 are the same as those in the first embodiment, and therefore the detailed explanation thereof will be omitted here for brevity.
  • the removal tab 7 is created at a position close to the longitudinal end of the body seal section 4 along its marginal line in the upper overlapping film of the wrapping film 1.
  • This removal tab 7 is made by the combination of the slits 5 and 6 which are cut at such an angle that they depart from each other by a given distance.
  • the slit 5 is cut substantially at right angles to the marginal line of the upper overlapping film.
  • the slit 6 is cut at an angle relative to the marginal line of the upper overlapping film in such a way that an imaginary continuation from the slit 5 and an imaginary continuation from the slit 6 depart from each other.
  • the perforated section 8 is formed in line with the imaginary continuation from the slit 6 that constitutes the removal tab 7.
  • the end of the removal tab 7 is first held with fingers or picked up with a fingernail or the like, and the fingers are moved in the A direction as shown in Figure 5.
  • the wrapping film 1 is torn up from the slits 5 and 6 that constitute the removal tab 7, and the removal tab 7 is lifted off from the lower overlapping film.
  • the split from the slit 6 reaches the perforated section 8.
  • the slits 5 and 6 are created in such a way that the imaginary continuation from the slit 5 and the imaginary continuation from the slit 6 depart from each other, and hence the split from the removal tab 7 is torn up so as to widely extend while the split from the slit 6 reaches the perforated section 8. This makes it possible to facilitate the opening of the wrapping film 1.
  • Figure 7 shows a wrapped article according to a fourth embodiment of the present invention.
  • another perforated section 8' may be created in line with the slit 5 in the third embodiment in the same manner as in the second embodiment.
  • the creation of the perforated section 8' allows the wrapping film 1 to be removed more easily in the same manner as in the second embodiment.
  • Figure 8 illustrates a wrapped article according to a fifth embodiment of the present invention.
  • a wrapped state of the wrapping film 1 is the same as that in the first to fourth embodiments, and hence the detailed explanation thereof will be omitted here for brevity.
  • the removal tab 7 is created substantially at the center of the body seal section 4 in a longitudinal direction thereof by the slits 5 and 6 that are spaced apart from each other by a predetermined distance and cut parallel to each other along the marginal line of the body seal section 4 of the upper overlapping film of the wrapping film 1.
  • Each slitting direction of the slits 5 and 6 is at right angles to the marginal line of the body seal section 4 of the upper overlapping film.
  • Perforated sections 8 and 8' are respectively formed on imaginary continuations from the slits 5 and 6 that constitute the removal tab 7.
  • the end of the removal tab 7 is held with fingers or picked up with a fingernail or the like, and the fingers are moved to the direction A shown in Figure 8.
  • This causes the wrapping film 1 to be split from the slits 5 and 6 that constitute the removal tab 7 in the same manner as in the first to fourth embodiments, and hence the removal tab 7 is lifted off from the lower overlapping film, so that the splits from the slits 5 and 6 reach the perforated sections 8 and 8', respectively.
  • the split caused by such a tearing action can continue around the wrapping film 1 by pulling the removal tab 7 created in the upper overlapping film of the wrapping film 1, whereby the wrapping film is torn up more widely.
  • the wrapping film 1 can be peeled off in such a way that substantially the entire wrapped article 10 is extremely easily uncovered.
  • the perforated sections 8 and 8' are extended to the vicinity of the surfaces on which the side seal sections 13 of the wrapped article are created, and hence a part of the wrapping film 1 remaining on the surfaces on which the side seal sections 13 are created can be extremely easily removed by pulling that remaining part of the wrapping film 1 in the direction in which it is taken off.
  • Figure 10 shows a wrapped article according to a sixth embodiment of the present invention.
  • a wrapped state of the wrapping film 1 is the same that in the first embodiment, and hence the detailed explanation thereof will be omitted here for brevity.
  • the removal tab 7 is created substantially at the center of the body seal section 4 in the longitudinal direction thereof by the slits 5 and 6 that are spaced apart from each other by a predetermined distance and cut along the marginal line of the body seal section 4 on the upper overlapping film of the wrapping film 1 at such inclined angles that they depart from each other.
  • the slits 5 and 6 are created at some inclined angles with respect to the peripheral portion of the upper overlapping film in such a way that an imaginary continuation from the slit 5 and an imaginary continuation from the slit 6 depart from each other.
  • the perforated sections 8 and 8' are created in line with the slits 5 and 6.
  • the end of the removal tab 7 is held with fingers or picked up with a fingernail or the like, and the fingers are moved to the direction A shown in Figure 10.
  • This causes the wrapping film 1 to be split from the slits 5 and 6 that constitute the removal tab 7 in the same manner as in the first to fifth embodiments, and hence the removal tab 7 is lifted off from the lower overlapping film, so that the splits from the slits 5 and 6 reach the perforated sections 8 and 8', respectively.
  • the slits 5 and 6 are created in such a way that an imaginary continuation from the slit 5 and an imaginary continuation from the slit 6 depart from each other.
  • the split from the slit 6 is reaching the perforated section 8, the split from the removal tab 7 is torn up so as to spread widely, thereby facilitating the opening of the wrapping film 1 to a greater extent.
  • the perforated sections 8 and 8' are extended to the vicinity of the surfaces on which the side seal sections 13 of the wrapped article are created, and hence a part of the wrapping film 1 remaining on the surfaces on which the side seal sections 13 are created can be extremely easily removed by pulling that remaining part of the wrapping film 1 in the direction in which it is taken off.
  • Figure 11 shows a wrapped article according to a seventh embodiment of the present invention.
  • a wrapped state of the wrapping film 1 is the same as that in the first embodiment, and hence the detailed explanation thereof will be omitted here for brevity.
  • the removal tab 7 is created at a position close to the longitudinal end of the body seal section 4 by the slits 5 and 6 that are spaced apart from each other by a predetermined distance and cut parallel to each other along the marginal line of the body seal section 4 on the upper overlapping film of the wrapping film 1.
  • the perforated sections 8 and 8' which are parallel to each other are created so as to cross the imaginary continuations from the slits 5 and 6 that constitute the removal tab 7, and are extended so as to spirally continue around the wrapped article 10.
  • the end of the removal tab 7 is held with fingers or picked up with a fingernail or the like, and the fingers are moved to the direction A shown in Figure 11.
  • This causes the wrapping film 1 to be split from the slits 5 and 6 that constitute the removal tab 7 in the same manner as in the first to sixth embodiments, and hence the removal tab 7 is lifted off from the lower overlapping film, so that the splits from the slits 5 and 6 reach the perforated sections 8 and 8', respectively.
  • the perforated sections 8 and 8' are extended to the vicinity of the surfaces on which the side seal sections 13 of the wrapped article are created, and hence a part of the wrapping film 1 remaining on the surfaces on which the side seal sections 13 are created can be extremely easily removed by pulling that remaining part of the wrapping film 1 in the direction in which it is taken off.
  • the wrapped article of this invention allows an extremely effective removal operation by a single action, and eliminates the necessity of using the tearing tape, thereby rendering this wrapped article very cost effective.
  • the perforated section is created at a position where it crosses the imaginary continuation from the slit for facilitating the opening of the wrapping film.
  • the indentation may be created at the same location where the perforated section is created.
  • an indentation 15 having a depth which is about half the thickness of the wrapping film 1 is created at the position where the aforementioned perforated section is created. This makes it possible for a user to remove the wrapping film as easily as in the case where the perforated section is created.
  • the front or rear surface between the two slits may be printed in ink that differs in coefficient of thermal contraction from the wrapping film.
  • the removal tab 7 is printed in ink 16 having a coefficient of thermal contraction which is larger than that of the wrapping film 1.
  • the removal tab 7 becomes concave relative to the surface of the wrapping film 1.
  • the removal tab 7 is printed in ink 16' having a coefficient of thermal contraction which is smaller than that of the wrapping film 1.
  • the removal tab 7 becomes convex relative to the surface of the wrapping film 1.
  • the slits are linear in shape, but the slits 5 and 6 may be V-shaped as shown in Figure 16, thereby making the slits 5 and 6 more easy to pick up.
  • the wrapping film may be provided with arrows 20 and 21 as shown in Figure 17.
  • a distance between the slits 5 and 6 cut along the marginal line of the body seal section of the upper overlapping film should be only enough for a finger nail or fingers to pick up the removal tab. Generally, the distance is selected from the range between 5 and 20 mm.
  • the article to be wrapped is a video cassette
  • the wrapped article of this invention can be applied to, for example, an audio cassette as shown in Figure 18, in which the body seal section 4 is created in a narrower surface of the rectangular-parallelopiped cassette.
  • an audio cassette and a video cassette or the like are used as the wrapped article, but the wrapped article is not limited to them.
  • the wrapped article of this invention can be applied to articles in any shapes such as a sphere, a rectangular parallelopiped, a column, or a circular cone so long as it can be wrapped with a wrapping film.
  • the unbonded part, the removal tab consisting of two slits and the perforated section are created in the body seal section without the use of a tearing tape, and hence the wrapping film can be widely torn up from this removal tab and the perforated section when the film is opened. Therefore, the wrapping film is not completely separated into pieces while they still remain tightly attached to an article to be wrapped, which is common in opening the film by the use of a conventional tearing tape. Thus, the wrapping film can be peeled off in such a way that the article to be wrapped is easily uncovered by a single opening action. Moreover, the wrapped article of this invention yields several advantages; namely, a step for providing a tearing tape can be omitted from processing steps, and also a tearing tape itself becomes unnecessary, whereby material costs can be reduced.
